Zusammenfassung:
A new high-pressure phase of LiAlO2 has been recovered through a shock
recovery technique at pressures above 9 GPa. This new phase has been
refined as a tetragonal structure with lattice parameters of a =
0.38866(8) nm and c = 0.83001(18) nm. Its calculated density is 3.51
g/cm(3). about 34% denser than gamma-LiAlO2. The aluminum and lithium
cations in this new phase are six-fold coordinated, as in alpha-LiAlO2,
and the structure of this new phase is similar to tetragonal LiFeO2.
This new high-pressure phase is stable at temperatures up to 773 K. (C)
